The probes sent by your planet have been damaged by some vicious aliens and have gone out of control. Therefore you need to shoot the probes and keep them in the space so that they will not drop and hit your planet. When the game starts, your spaceship will be located at the bottom of the screen, and a probe will start to descend from the top. You can use the left and right arrow keys on your keyboard to move the craft, then press Spacebar to shoot. When the probe is hit, it will split into smaller pieces, and you need to shoot repeatedly so that at least 1 ball is kept in the air. The split balls may carry special items, and when those balls are hit the special effects will take place: a ball marked with a lightning icon boosts your shooting speed, the one with a wing allows your spaceship to move faster, and the ball with a tortoise icon will slow down your craft. If an asteroid appears, you need to dodge or the spaceship will be petrified for 1 second if it is hit. If all of the balls are dropped, the game ends. Take control of the splitting balls and protect your planet from destruction.
